Lab-Grown Pink Sapphire Cluster Rings

A lab-grown pink sapphire cluster ring surrounds a pink center with small lab-grown diamonds so the whole top reads as one larger shape. Choose a floral halo, a star-shaped halo with a pavé band or a graduated cluster, with an oval, round, cushion, emerald cut, princess, pear, marquise or heart center in white, yellow or rose gold in 10K, 14K or 18K, platinum, or Silvadium, a tarnish-resistant sterling silver.

Buying guide

How a cluster ring is built

A cluster gathers small stones tightly around a center so they read as one piece from a distance. The looks in this collection:

  • Floral double halo: two rows of lab-grown diamonds form petals around the lab-grown pink sapphire.
  • Star floral halo: a pointed petal outline with a pavé band for sparkle along the finger.
  • Graduated cluster: lab-grown diamonds that step down in size around the center.

A lab-grown pink sapphire and lab-grown diamond cluster ring looks larger than a solitaire of the same center size, which makes it a good choice when you want presence without a very large stone.

What a lab-grown pink sapphire is

A lab-grown pink sapphire is the same corundum crystal as a natural pink sapphire, grown under controlled conditions. It rates 9 on the Mohs scale, just below diamond, so it stands up well to daily wear in a ring. Its color is even and the stone is usually very clean, at a far lower cost than a natural pink sapphire of similar size and color.

Size, metal and price

Each design offers 1 to 9 carats total weight. Rose gold deepens the pink; white gold, platinum and silver make it look brighter and cooler; yellow gold gives a softer, vintage contrast. Prices start under $450, and most rings are just under $1,000 at their smallest size.

Made to order

Each ring is made for you in 10–15 days. Shipping is free on orders over $500, returns are accepted within 30 days, and one resize is free within 60 days of delivery.
